The waters around Australia, the world s smallest continent, are
home to the greatest diversity of sharks and rays on Earth. Fully
100 of these sea creatures (along with their little-known
relatives, the chimaerids) have been named or described since the
first edition of this book the biggest revision of the Class
Chondrichthyes since the time of Linneaus. This second edition of
"Sharks and Rays of Australia" brings more than 300 of these
species to life in newly commissioned, full-color
illustrations.
Here, in precisely painted detail, are the weird silvery ghost
shark and the remarkably camouflaged ornate wobbegong; spurdogs and
swell sharks; the primitive frilled shark and the blacktip, a fast
swimmer capable of leaping out of the water like a dolphin. Peter
Last and John Stevens review the major shake-ups in the
elasmobranch family tree sorting out, for instance, dogfishes and
skates and include updated family keys, the latest information
about species ranges, and new distribution maps. Extensively
revised species descriptions reflect additional fisheries and newly
gleaned life history and biological information all essential to
conservation efforts as sharks die in commercial bycatches and end
up on restaurant menus. An essential tool for conservation
biologists trying to save threatened sharks, now under siege
worldwide, this marvelous volume will also appeal to fish
biologists, divers, naturalists, commercial and recreational
fishermen, and anyone with an appreciation for these ancient
evolutionary survivors.
